MEANS FOR GIVING A FINISHED SURFACE TO WIRE-GAUZE.

Specification of Letters Patent.

Patented May 4, 1915.

Application filed October 16, 1914. Serial No. 867,020.

To aZZ whom it may concern:

Be it known that I, FRANCIS STONIER, a subject of the King of Great Britain, residing at Harris street, Strangeways, Manchester, in the county of Lancaster, England, have invented new and useful Improvements in Means for Giving a Finished Surface to Wire-Gauze, of which the following is a specification.

The invention relates to means for giving a finished or smooth surface to wire gauze.

It is well known that roughness of the surface of wire gauze has a detrimental effect in certain industries to which the same is applied; as, for instance, in the case of wire cloth employed in paper making machines, and the object of my invention is to provide improvements in apparatus for remedying this defect.

In carrying out my invention I provide an apparatus consisting more particularly of a revoluble presser roller and a fiat bed or plate in close proximity thereto, between which roller and plate the wire gauze to be treated is passed under pressure of the roller, by being moved or pulled or aided in its movement, by extraneous means operated independently of the presser roller aforesa1 With reference to the accompanying drawings, Figure 1 is a longitudinal and sectional elevation of an end portion of my improved apparatus, and Fig. 2 is a similar view of the opposite end portion thereof. Fig. 3 is an end elevation, slightly sectioned, of said apparatus, with parts therein not indicated in the preceding figures, and all according to one form of my invention.

With reference to the said Figs. 1, 2, and 3, a is a flat bed or plate here shown fixed in position, and b the revoluble presser roller in suitably close proximity thereto, or capable of being so situated, between which plate and roller the wire cloth, indicated at 0 in Fig. 8, is passed, in order to have a finished surface imparted thereto.

For giving the best effect, the roller, such as Z), requires to be of suitable weight, as too great a weight or pressure tends to flatten the wire, and too little weight does not operate upon the same properly. Thus fora solid steel roller about 14: feet long, I prefer its weight to be approximately half a ton. The roller b is shown supported by bearings in the standards (Z, the bearings themselves shown at al being capable of movement in a vertical direction; that is to say, a screw for each standard, passes through, and is 1n screw engagement with the top portion of sald standard, and is provided with a foot piece or block 0 This block is situated be low a bridge portion 0Z attached to the top of the bearing (Z and the screw shaft 6 freely passes through said bridge portion. It will thus be seen that the turning of the hand-wheel shown at 0 will have the effect of raising or lowering the bearing 6Z1 as desired, and thus enable the vertical height of the end of the roller 6 to be adjusted, relatively to the plate a. By operating the hand-wheels at both ends of the apparatus, the said roller may be so adjusted as a whole. But I do not confine myself to any particlar method of adjusting the roller aforesaid.

A handle it is shown in Fig. 2 attached to the shaft end of the roller 5, for rotating the same as the wire cloth is passed between the plate av and said roller, in those cases where the roller is driven instead of being revolved solely by the movement of the wire cloth between said roller and plate. It is obvious that the roller Z2 could be driven by hand or by mechanical power.

In Fig. 3 the wire cloth 0 is assumed to be moved from left to right, and to be passed between inclined plates shown at 70, for straightening the same before being operated upon by the roller and plate beforenamed. The extraneous means provided for moving or aiding the movement of the wire cloth, consists in the present instance of a roller Z suitably mounted, and around which the wire cloth is wound as it is moved from between the roller and plate referred to. This roller Z is preferably larger than the roller 6, and rotates in the same direction and at the same axial speed and therefore at greater circumferential speed than the roller 6. An adjustable nip roller at the periphery of roller Z could be employed for gripping the first part of the wire cloth, in the first instance. When the revoluble roller, such as b, is arranged to be turned by handle it, or otherwise, then the extraneous pulling means referred to may be said to aid the movement of the wire cloth through the apparatus, but when the roller aforesaid is merely capable of being revolved by the movement of the wire cloth passed between it and the plate adjacent thereto, the extraneous pulling means may be said to provide the whole of the movement necessary. I have found that a flat plate or bed adjacent to a revoluble presser roller, which plate is practically a fixture relatively to the moving periphery of said roller, gives the best results especially when combined with external pulling means which are operated independently of the presser roller; for the apparent reasons that the sheet of gauze is retained in an undisturbed condition while being operated upon, relatively to its flat condition previous to that operation, and the independence of operation of the external pulling means enables the degree of pull to be regulated according to the character of the gauze being so operated upon. A spur wheel, the pitch line of which is merely indicated in Fig. 8 is assumed to be situated at the end of the roller Z, which gear wheel is in gear with and operated by another spur wheel m suitably driven by power as required. As illustrated, the roller Z revolves as the roller 6 is also revolved in the same direction, by which means the wire cloth is drawn through the apparatus with the desired result.

I claim 1. In apparatus, for giving a finished or smooth surface to'wire gauze, of the type employing additional means for pulling or aiding the movement of the gauze between a revoluble presser roller and a roller or other curved bed, a flat bed in combination with said presser roller and in substitution for a roller or curved bed, and independently operated pulling means for the gauze, substantially as herein set forth.

2. In apparatus, for giving a finished or smooth surface to wire gauze, of the type employing additional means for pulling or aiding the movement of the gauze between a revoluble presser roller and a roller or other curved bed, a flat bed in combination with said presser roller and in substitution for a roller or curved bed, and an independently operated roller upon which the gauze is wound at increased peripheral speed relatively to said presser roller, said winding roller being adapted to pull the gauze between the presser roller and said fiat bed, substantially as herein set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRANCIS STONIER.
